The politically correct “Out of Africa” position for the evolution of the human species was recently shaken by the discovery of fossils with human-like teeth in Bulgaria and Greece, dated to 7.2 million years: http://www.telegraph.co.uk/science/2017/05/22/europe-birthplace-mankind-not-africa-scientists-find/. I have written about this previously, pointing out that it shatters the standard hypothesis that mankind arose in Africa, and also that Europeans were a late arrival on the evolutionary scene, and consequently must be backward.
Now there is news which further challenges the received hypothesis about human origins, with fossils found in Morocco being regarded by some scientists as the oldest Homo sapiens fossils, at 350,000 years old. If this proves to be so, and the fossils are genuinely Homo sapiens, and some scientists, to be expected doubt this, this shoots down the idea that humans are only 100,000 years old, and that that is an inadequate time for racial characteristics to develop.
I look forward to more sacred cows in human prehistory being slaughted in the time to come.
